Answer / dilip singh

whenever a fault take place in any system. the fault
current start rising and it reaches to some high value.
your equipment are not rated for this high value so it will
get damaged. to restrict this fault current to rise. the
neutral of transformer or generator are earthed.
whenver the fault occurs the nautral passes this fault
current to ground and protect the costly equipments.

Answer / dpk_1fj

neural being earthed at consumer premise.the reason behind
to do that is if neural is lost,earth provide a parallel
path for return current and event of fault,fault current
pass therough the earth that ensure operation of protective
device.

extremely urgent please, why a fuse is used before voltmeter but not with a ammeter connected to a CT(current transformer),thanks in anticipation.
